Hi, We have a requirement to update the datatype of a fact in a dataset without deleting the data in the dataset. The MAQL UPDATE doesn’t let us do this with PRESERVE DATA option. Any ideas on how to accomplish this?

HI Naveen. Some model changes are possible to do with preserving data, some not. It depends on the change. It is for example not possible with preserving data to change bigint to int, if you have some bigint numbers in the dataset. There is no way how to make such change with preserving data. Whats your change about?

Hi Martin, We are trying to change int to bigint. I have provided the details here.
